Pro’s 
– Very quick to put on
– Support at the top for baby’s neck
– Attractive design (!?)
– You can breastfeed in it – although you do need one hand to support baby whilst you’re breastfeeding
– Convenient – nipping out, or driving somewhere and then nipping into the shops – quicker than a pram
– Close to your chest so baby feels secure and happy
– Good for attachment parenting

Con’s
– Weight is ‘across’ so not 100% evenly balanced
– Have to be mindful baby doesn’t slip down – small risk of suffocation
